42、1) bar; ambient air temperature: 20 C; maximum average variation over the test period 1 K maximum variation during the tests 2 K electrical supply voltage: (230 2) V (single phase). 4.2 Measurement uncertainties Except where otherwise stated in the clauses describing the tests, the uncertainties of

43、measurements carried out shall not be greater than the maximum uncertainties indicated below. The standard deviations take account the various sources of uncertainty: contribution from the instrument, repeatability, calibration, ambient conditions, etc. water rate: 1 %; gas rate: 1 %; time: 0,2 s; t

44、emperatures: ambient: 1 K; water: 0,5 K; gas: 0,5 K; mass: 0, 5 %; gas pressure: 1 %; gas calorific value: 1 %; gas density: 0,5 %; BS EN 13203-1:2015EN 13203-1:2015 (E) 8 electrical energy: 2 %. The stated measurement uncertainties relate to individual measurements. For measurements that combine a

45、number of individual measurements, smaller uncertainties on the individual measurements may be necessary to ensure a total uncertainty within 2 % under the steady state conditions. These uncertainties correspond to two standard deviations (2). 4.3 Test conditions 4.3.1 General Except where otherwise

46、 stated, the appliance shall be tested under the following conditions. 4.3.2 Test room The appliance shall be installed in a well-ventilated, draught-free room (air speed less than 0,5 m/s). The appliance shall be protected from direct solar radiation and radiation from heat generators. 4.3.3 Water

47、supply For the tests: domestic water pressure is the static inlet pressure under dynamic conditions measured as close as possible to the appliance; inlet and outlet temperatures of the domestic water shall be measured in the centre of the flow and as close as possible to the appliance. The inlet tem

48、peratures shall be measured immediately upstream of the water inlet connection. Except where otherwise stated, the outlet temperatures shall be measured immediately downstream of the outlet connection or, in the case of an appliance with spout delivery, by means of an immersed temperature measuring

49、device, e.g. a u-tube fitted at the outlet of a tube of the same length as the minimum length of the spout normally supplied by the manufacturer. The hot water temperature shall be measured with a rapid response thermometer. “Rapid response thermometer“ means a measuring instrument with a response time such that 90 % of the final temperature rise, from 15 C to 100 C, is obtained within about 1 s, when the sensor is plunged into still water. 4.3.4 Steady stat
